Groadinger UG

1X OR 2X, DO-IT-ALL GRAVEL & ADVENTURE BIKE

Groadinger UG

from £1350 inc UK Tax (frame only)

The Utra Grav Grav Kitchen Sink

The UG is the gravel bike built for adventure-groading and fast off-roadin. 

Developed from our MK1 OG frame design and a 650b high volume tyre the UG is our effort to make a bike tweaked for longer rides and bike packing without sacrificing on ride feel, or making an any less off-road capable and shreddable design. The UG is a lightweight steel fun bike designed specifically with the road-to-gravel-to-gnar ratio found most often when gravel riding in the UK. This do-it-all gravelling adventure-ready frame set is for 1X or 2X and a carbon or steel fork for packing up or packing light but never packing in.

A true all around frame set that can be built as a fast groader or long haul ultra roader. However you roll, you’re gonna want a UG as your friend in the wilderness!

MK2 UG is now for 395mm axle to crown tapered steerer forks and comes with clearance for both 650b x 2.1 and 700c x 44mm tyres in the same frame. Available with a choice of carbon fork and now with our new steel UG SAF adventure fork for the full steel feels.

The frames we stock have a T47 BB shell as standard. If you would prefer a Square Taper (BSA) shell that can be done, but would mean an 8-12 weeks ETA to build the frame especially to this spec.

We have deliberated at great length over the geo numbers –
in fact we worked on this with a specialist, Tim from Soigneur Bike Fitting – the result is a gravel bike optimised for longer days in the saddle while not compromising on the ride.

So, have a look at the table below to see which size is best for you.

Please see the Contact Points tab if this is all a bit confusing.

Frame geometry affects bicycle handling and therefore can be quite different between two bicycles of the same fit/size.

So,
if the numbers on the Sizing table are a little confusing and do not compare to your current frame then please fill in the form below (as best you can) and we will get back to you with a custom fit drawing and frame size suggestion in 1-2 working days.

8-12 week turnaround

We have tried to set up the sizes to cover most people,
however! everyone is different. 

So if you need custom sizing that can be arranged. We build everything in house after all.

What we’ll be needing from you:
preferably from Bike Fit data (e.g. from a bike fitter like Soigneur)
but we are also happy to use fit information – contact points – from a bicycle you are perfectly comfortable on already.

As always, if you’re unsure about anything say the word and we can help you figure it out.
